Graphene Zero-Bias Sub-Terahertz Turnkey Detector with Above 43 GHz Bandwidth
E. I. Titova, A. Titchenko, M. Titova +16
High-frequency terahertz (THz) detectors are vital for next-generation high-speed wireless communication systems. Graphene, with its high carrier mobility, broadband absorption, an…
Enhanced Terahertz Thermoelectricity via Engineered van Hove Singularities and Nernst Effect in Moiré Superlattices
L. Elesin, A. L. Shilov, S. Jana +14
Thermoelectric materials, long explored for energy harvesting and thermal sensing, convert heat directly into electrical signals. Extending their application to the terahertz (THz)…
Limiting performance of graphene bilayer sub-terahertz detectors at large induced band gap
Elena I. Titova, Mikhail A. Kashchenko, Andrey V. Miakonkikh +8
Electrically induced junctions in graphene bilayer (GBL) have shown superior performance for detection of sub-THz radiation at cryogenic temperatures, especially upon electri…
Nanopatterning of multicomponent van der Waals heterostructures using atomic force microscopy
A. L. Shilov, L. Elesin, A. Grebenko +10
Multilayer van der Waals (vdW) heterostructures have become an important platform in which to study novel fundamental effects emerging at the nanoscale. Standard nanopatterning tec…
